3. On instead of a pronoun

Coucou, on est là = coucou, nous sommes là: hello, here we are!
On est venus à pied: we came by foot
On est très contentes: we are very happy
On s’en fiche: who cares!

The use of “on” is more familiar in a conversation

On instead of Tu or Vous (you)

Alors, on ne dit pas bonjour à son papa? well, you don’t say hello to your dad?
On ouvrira son livre à la page 200: you will open you book page 200.
On ne dort pas de cette chaleur: you can’t sleep in this heat. On ne lui donnerait pas 90 ans: you wouldn’t think she is 90.
On se calme! calm down!
On se dépêche: hurry up! On ne t’a rien demandé: nobody asked you for your opinion

(writers also use “on” instead of “je”)

4. On and l’on

We sometimes use l’on instead of on, it is just a question of pronunciation, what we call euphony.

Generally we use “l’on” after words ending with the sound of a vowel, like:
et, ou, où, que, à qui, à quoi, si.
Si on suppose or si l’on suppose
On a que ce que l’on mérite: we get what we deserve

5. To Go Further

Negative form:

On n’est plus d’accord

On est plus nombreux (outnumbered)
Pay attention, here, the way you pronounce “plus” to know if it is ‘no more’ or ‘more’, as “on est” and “on n’est” have the same pronunciation (for no more, we don’t say the ‘s’ at the end of the word)

Question:

Mange-t-on du riz? ( we add a t)

6. On dirait: sound like, look like

On dirait mon père quand tu parles: it sounds like my father when you speak.
On dirait un banquier avec ces vêtements: you look like a banker with these clothes.
